/**
 * init.ts — Interactive guided setup for .wombo-combo/config.json.
 *
 * Usage: woco init [--force]
 *
 * Renders a minimal Ink confirmation screen that:
 *   - Auto-detects project name from folder, base branch from git,
 *     build/install commands from package.json.
 *   - Shows all defaults with 3 editable fields (baseBranch,
 *     build.command, install.command).
 *   - On confirm, writes only essential files: config.json, tasks/, archive/.
 *   - Does NOT create runtime artifacts (logs/, history/), auto-install
 *     shell completions, or check dependencies inline.
 *
 * NOTE: The ink/init-app module is dynamically imported to avoid pulling
 * the `ink` dependency into the static import graph. The `ink` reconciler
 * contains a top-level await that breaks `require()` in schema.ts.
